(20t + 5)° + 15t° = 180° [they form a linear pair]
20t + 5 + 15t = 180
20t + 15t = 180 - 5
35t = 175
t = 175 ÷ 35
t = 5

a carpenter is fitting some bookcases to an alcove, using as much of the space as possible from floor to ceiling, a height of 2.5 m. The books to be fitted into the shelves are 210 mm high and a gap of at least 30 mm is necessary above each book so that they can be removed. The shelves are 20 mm thick. The alcove is 1.2 m wide. The bottom shelf should not be less than 300 mm from the ground, as the house-owner cannot bend down easily. How many shelves can be fitted into the alcove?
Answers
The number of shelves that fit in the alcove is given by the height of each shelve and the height of the bookshelf above the ground
The number of bookshelves that fit into alcove, is 8 bookshelves
Reason:
Height of the alcove = 2.5 m
Height of the books = 210 mm = 0.21 m
The gap above each book = 30 mm = 0.03 m
The thickness of the shelves = 20 mm = 0.02 m
Width of the alcove = 1.2 m
Height of the bottom shelf above the ground = 300 mm = 0.3 m
Required:
The number of shelves that can be fitted into the alcove
Solution;
Let x, represent the number of shelves that can be fitted into the alcove
We have;
An initial height of the bookshelves above the ground = 0.3 m
Height of a shelve, H = Height of books + Gap above books + Thickness of shelves
Height above ground, including the bottom shelve = 0.3 m
[tex]x = \dfrac{2.5 - (0.3)}{0.02 + 0.03 } = 8\frac{6}{13}\approx 8.46[/tex]Therefore, the maximum number of whole bookshelves that can be fitted into alcove, x ≈ 8 bookshelves

Penny reads 11 pages in 1/3 hour. What is the unit rate for pages per hour? For hours per page?
Answers
Answer: 33
Step-by-step explanation:
Answer:
33 pages per hour
Step-by-step explanation:
1. To solve for how many pages Penny can read in one hour, we need to write a ratio of pages to hours.
[tex]11: 1/3 = x : 1[/tex]2. Now, 1/3 goes into one, three times. This means that 11 goes into x, three times. We can write "11 goes into x, three times" as: [tex]\frac{x}{11} =3[/tex].
3. (Solving x/11 = 3)
Step 1: Multiply both sides by 11
[tex]\frac{x}{11}*11=3*11[/tex] [tex]x = 33[/tex]Therefore, Penny read 33 pages per hour.

At the beginning of the week, Aksa’s parents deposited $20 into Aksa’s lunch account. The amount of money Aksa had left after each day is shown in the table, where x is the number of days and y is the remaining balance.
a. What are the x- and y-intercepts?
b. What do the x- and y-intercepts represent?
Answers
Here we need to plot x and y co-ordinates from the given table.
What are x and y co-ordinates and intercepts ?This is 2D co-ordinate geometry here we have an x axis and a y axis we use co-ordinate geometry to plot lines and curves according to the gives question.when the question consist of linear equations they form straight lines and when questions consists of quadratic and higher degree polynomials they form curves.
a. Here the the days are represented by x and remaing balance are represented by y.
So, when x = 0, y = 20 is co-ordinate form we can represent this as (0,20)
similarly the other co-ordinate points are (1,16), (2,12), (3,8), (4,4), (5,0).
b. x- and y- intercepts represnts the value of one variable corresponding to the other variable.

We need to find the rate of how much the taxi driver charges per minute.
Therefore:
We need to pick a precise point on the line ( a precise point is a point with whole number x and y coordinates; no decimals or fractions).
We see that the point (6, 9) is precise.
A rate is a ratio in the form of a fraction that shows the relationship of change between two quantities: a/b.
So, the taxi costs 9 dollars / 6 minutes.
9/6 simplifies 2/3.
And thus, the taxi charges 2 dollars per 3 minutes
So, the answer is 9/6, which can be simplified to the furthest possibility, making it a unit rate.
Answer: 9/6

What is the total price of a $45.79 item when a 7% taxe is added
Answers
Answer:
$42.58
Step-by-step explanation:
You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.
in this case:
45.79x0.07 = 3.205 (rounded 3.21)
45.79-3.21 = 42.58

If 15% of 4x is 20 less than x, what is the value of x?
Answers
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
Jethro used dimensional analysis to convert one rate of speed to another. Two of the conversion factors he used are 5280 ft/1 mi and 1 hr/60 min. What could be the units of the initial rate of speed and the final rate of speed? Justify your answer.
Answers
The units of the initial and final rates of speed are;
Initial rate of Speed = ft/hr
Final rate of speed = mi/min
We are told that the conversion factors he used are;5280 ft/1 mi and 1 hr/60 min
Now, the meaning of 5280 ft/1 mi denotes that;5280 ft mile is equivalent to 1 mile
This means that the initial distance unit used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.Read more at; https://brainly.com/question/17734333
